I really hoped someone would understand, take into consideration, offer help, or at least share some similar problems here. And I'm glad there are ppl who want to take part in this. After all, who's more likely to understand you than your colleagues?!
I work in Croatia. I teach teenagers, ages 14-18. (One would say, the most difficult ones!) But, although there have been some difficult situations I've encountered, I strived to come out of them stronger and with greater wisdom, if I may say. To be honest, we all once were beginners and didn't have a clue how to deal with problems we faced. And now we have the Internet to share the experience and help each other, right?
I have been teaching English for almost ten years now. There have always been students who tend to be more aggressive, or agitate with their behaviour, and therefore impose an uncomfortable atmosphere in the classroom, and thus unable others to comprehend the lesson, or me, as a lecturer, to teach the lesson properly. When this happens, I bear in mind one important thing, "that student is an individual, he/she is the only one who makes trouble, others are polite students, some of them being "naive" so they get influenced by the trouble-maker, and the rest of the class would, actually, like to learn something." So, how do I deal with the trouble-maker?! I ask him politely, (and as sweetly as possible, a smile disarms everyone), to stop. Usually, this helps, and they immediately stop. I never yell in the class, I try to keep my voice friendly and soft, and try to assure them I'm there only to help them. If the trouble-maker goes on, I ask him nicely to wait for me after the lesson finishes, and I talk to him. This always helps, because if you talk to him /her in front of others he/she will perhaps feel provoked, more agitated. By doing this you show him he's also a person, and you're only trying to be a friend. Of course, nothing is 100 % sure, but if this solves at least half of the problems, we can be satisfied, right?
I hope this will help! How do you deal with trouble-makers?
I hope to hear from you soon.
P.S. Many of your themes are interesting, but next time, perhaps, because there's so much to say
